Government vehicle regulations are focused on preservation of resources, environmental compatibility and safety. This drives the need to build powertrains that are more efficient and produce little to near zero emissions. From the customer’s perspective, restrictions, such as ZEV zones and incentives to purchase and operate vehicles using a particular powertrain or fuel, will influence vehicle purchases and use. In the near term to meet regulatory requirements, conventional powertrain displacement will be reduced, while torque density is increased. These changes drive the need for increased transmission ratio spreads and ratio steps, along with significant enhancements in driveline efficiency.

Beyond 2016, the CO2 restrictions will be such that a significant portion of the OEM’s portfolio must include electrified drivetrains. Innovative hybrid powertrain solutions will play a major role in meeting the ever stricter future emissions requirements, while complementing the development of the conventional powertrain. The next generation of hybridization will become an enabler of future technology, making possible the implementation of advanced thermodynamic improvements to the ICE.

This presentation will discuss the current state of the conventional and electrified driveline along with the technical challenges that will need to be overcome in the future to meet both regulatory and customer demands.
